Application filed June 18, 1912. Serial No. 704,442.

and overthrow of motion between the escapement actuating mechanism andthe escapements is provided for.

To these and other ends, the invention consists in certain improvements,and combinations and arrangements of parts, all as will be hereinaftermore fully described, the novel features being pointed out particularlyin the claims at the end of the specification.

In the accompanying drawing: Figure 1 represents a vertical sectionthrough portions of the magazine, escapement actuating mechanism andkeyboard showing the improvements of the present invention appliedthereto, the mechanism being shown in normal or inoperative position;Fig. 2 is a view similar to Fig. 1 showing the escapement and itsactuating mechanism in operated position.

' Similar parts are designated by the same reference characters in theseveral views.

The present invention is applicable generally to esca-pement mechanismsof different types, and it is to be understood that the invent-ion isnot limited in this regard although the present improvements are shownin connection with an escapement of a novel form which forms the subjectmatter of a separate application and hence is not claimed herein.

The preferred embodiment of the invention is shown in the accompanyingdrawing and will be hereinafter described in detail, but it is to beunderstood that the invention is not limited to the particularconstruction shown, as equivalent means may be provided foraccomplishing the same results.

i i 1 l will hereinafter appear.

In the present instance, 1 designates the 1 lower or. matrix deliveryend of the magalzine, the magazine having a channel for each row ofmatrices 2, and the escapement 3, one of which is arrangedin the bottomof each matrix channel of the magazine, 1 controls the delivery of thematrices there from.

The escapement shown be briefly described as composed of a segmental,member of substantially semi-circular form l and formlng dogs a and 5at lts ends to cooperate with the ears or lugs 6 on the .matrices, eachescapement being adapted to g oscillate about a fixed axis which is insub ;stantial alinement with the ends of the esoapement and is locatedin the matrix guiding groove formed in the bottom or" the magazinechannel. The escapement is supported and guided in its oscillatorymovements by a segmental bar 7 which extends transversely across thebottom of the magazine and the escapement is returned auto- 1 mati'callyto initial position after each actuj atlon thereof by a spring 8 whichbears on a lug 9 on the escapement and has its end fixed in a projection10 which is rigidly attached to the magazine. A cover plate or guard 11is also applied to the under side @of the magazine and coiiperates withthe jouter side of the segmental e'scapement to retain the same'incooperative relation with .the bar 7.

A lug 12 projecting from that end of the escapement opposite'to the endbearing the lug 9 serves to actuate the es- }capement in opposition tothe'action of the spring 8, the two positions of the escape ment beingindicated in F igs. 1 and 2.

1Preferaibly, the under side of the actuating lug 12 of the escapementis formed with a beveled surface 13 for a purpose that The key lever 14may cooperate as usual with a vertically movable key bar 15, the lattercooperating with a bell-crank lever 16 the end 17 of which bears on andnormally supports the cam yoke 18, the latter being fulcrumed on themachine frame at 19 and bearing a cam 20 which is revoluble' on a pivotpin 21 supported by the cam yoke. This cam is adapted to cooperate withthe periphery of a continuously revolving roller 22 when the respectivekey bar 15 is elevated by manipulation of the respective key lever, suchmovement of the key bar causing the bell crank lever 16 to operate in amanner to lower the cam yoke and thus permit the cam to come in contactwith the roller, a projection 28 on the cam normally resting against atoothed bar 2 1 to hold the cam in an inoperative position althoughdisengaging from the bar 2% when the cam yoke is lowered.

A- row of escapement actuating reeds 25 is provided to correspond withthe row of escapements, these reeds restlng on the vertically movableends of the respective cam levers 18 and they are guided at their lowerends by the bracket 26. The upper portions of the reeds 25 are guided bya bar 2 which prevents lateral displacement of the reeds, thusmaintaining them in cooperatlve relation with the respectiveescapements, but each reed operates in a slot 28 in the bar 27 wherebythe reeds may become deflected in the planes of their respectiveescapements. The upper end of each reed is formed with a beveled surface29 which is adapted to cooperate with the beveled surface 13 of thecorresponding escapementactuating lug 12, and each reed is acted upon bya tension spring 30 which operates preferably to draw the reed in adiagonal direction downwardly to maintain it in proper relation to itsrespective cam yoke and to maintain its upper end in operative relationto the respective escapement actuating projection. hen one of the reedsis elevated by its respective cam yoke, the spring 30 will act toholdthe upper beveled end of the reed in contact with the correspondingactuating projection 12 on the respective escapement until theescapement has been actuated and caused to assume the position shown inFig. 2 whereby the foremost matrix in the respective magazine channel isreleased by the dog 4 of the escapement and the following matrix isarrested by the dog 5 of the escapement, and when the escapement is sooperated, the actuating lug 12 thereon will abut against a stop 31 whichis formed at the under side of the magazine. In operating the escapementin this manner, the force of the spring 30 is suflicient to overcome thestrength of the escapement-returning spring 8. However, when theescapement actuating projection 12 abut-s against the rigid stop 31,further movement of the escapement is pre vented and the excess motionor overthrow of the reed is compensated for by a deflecting action ofthe upper end of the reed, which causes the latter to assume aninoperative position relatively to the respective escapement, thebeveled surface on the upper end of the reed riding toward the outer endof the projection 12 of the escapement as shown by the full lines inFig. 2, the spring 30 yielding to permit such movement of the reed, andwhen the cam yoke returns to initial position the reed will be restoredto initial position by the action of the spring 30, the escapement beingrestored by the operation of its spring 8.

I claim 1. In a linotype machine, the combination of a magazine having amatrix controlling escapement, actuating mechanism thereof, and a reedoperative by said actuating mechanism to engage and positively actuatethe escapement to release a matrix and yieldable into an inoperativeposition relatively to the escapement to allow overmotion of the reed.

2. In a linotype machine, the combination of a magazine having a matrixcontrolling escapement, actuating mechanism therefor, a member operativeby said mechanism and cooperative with the escapement, and means forholding said member in operative relation to the escapement until thelatter has delivered a matrix and yieldable to permit said member todeflect laterally and assume an inoperative relation to the escapementand thereby allow overmotion of said memher.

3. In a linotype machine, the combination of a magazine having amatrixcontrolling escapement, actuating mechanism thereof, and alongitudinally movable reed operative by said mechanism and having abeveled surface to engage and operate the escapement to deliver a matrixand yieldable into a deflected relation to the escapement to allowovermotion of the reed after the latter has operated the escapement.

4. In a linotype machine, the combination of amagazine having a matrixcontrolling escapement, actuating mechanism thereof, a reed reciprocableby said mechanism, the reed and escapement having cooperative surfacesbeveled diagonally of the direction of movement of the reed, and meansfor retaining such surface in operative relation to actuate theescapement, and permitting a slipping action between such surfaces asthe reed continues to operate after the escapement has delivered amatrix.

5. In a linotype machine, the combination of a magazine having a matrixcontrolling escapement, actuating mechanism therefor, a reedreciprocable by said mechanism, the reed and escapement havingcooperative surfaces'beveled diagonally of the direction of movement ofthe reed, and means for retaining such surface in operative relation toactuate the escapement, and causing deflection of the reed after thelatter has caused delivery of a matrix bysaid escapement.
